MagnaFlow Cat Back Performance Exhaust Systems for Gas Vehicles

MagnaFlow Cat Back performance exhaust is the perfect accessory for your pickup truck, SUV, muscle car, or sport compact. MagnaFlow has strived to become the Number 1 name in performance exhaust and you can rest assured you are getting an exhaust system that is as rugged and reliable as your vehicle when purchasing a MagnaFlow exhaust system. All exhausts start with carefully selected pipe and muffler sizes to ensure proper tuning to prevent loss of low-end torque. Mandrel bent pipes and precision engineered, straight through performance mufflers reduce power robbing back pressure and heat while creating a deep, throaty sound. MagnaFlow mufflers are wrapped with acoustical fiberfill for maximum sound absorption to keep things quiet inside the cab of the vehicle. All Magnaflow exhaust systems are constructed of stainless materials and feature OEM style barbed hangers and flanges. Mufflers and tips are mirror finish stainless steel which is not only attractive, but extremely durable. Each MagnaFlow system is fit tested and dyno verified to deliver maximum performance. MagnaFlow cat back exhaust systems come with all mounting hardware and are backed by a lifetime warranty.

Question: Will I get better gas mileage with MagnaFlow Performance Exhausts?

Answer: YES, a better performing engine uses fuel more efficiently, if driving conditions and tendencies are similar. However, it is not a guarantee. Our mufflers were designed as performance mufflers.  MagnaFlow's diesel exhaust for trucks will see the biggest gains due to our systems' dropping EGT's over 150 degrees.

Question: How much horsepower can I expect to gain?

Answer: It's different for every car, but typically expected gains are in the average range of 10%.
Replacing the muffler/exhaust with a MagnaFlow will help your engine increase power by being able to expel exhaust gases quicker. This creates less workload for the engine, makes it run more efficient, and results in better power.

Question: Are MagnaFlow Performance Exhaust systems legal?

Answer: YES, all of our Cat-Back Exhaust Systems comply with most state and federal laws with the exception of the Magnapacks. (Please note, local laws may vary. Contact your local law enforcement for specific guidelines.) Our products are designed and tested to meet legal sound level limits; however, when used in conjunction with other products (such as air intake systems or exhaust headers), the overall combined effect might cause particular vehicles to exceed the allowable limits.

Question: Why is MagnaFlow the best exhaust system?

Answer: Nothing performs better, looks better, or sounds better than MagnaFlow Performance Exhaust. Our Research and Development Team invests many hours to ensure our products stay competitive and perform the way they should.  Our systems feature straight-through flow designs for the ultimate in unrestricted horsepower and torque for big power while maintaining exhaust efficiency.

Question: What's the difference between Stainless Steel and Aluminized Steel?

Answer: The main difference between the two is pricing and the outer shell of the mufflers. Stainless Steel cost more than Aluminized Steel. The Stainless steel mufflers have a polished stainless steel shell and are 100% stainless construction. Stainless steel is better looking and will never rust. Nothing looks better or lasts longer than stainless steel. The aluminized mufflers have stainless internals and necks but have an aluminized outer shell. Also, the aluminized steel has only a protective coating that, if scratched off, may rust. Both mufflers have identical internal construction and materials and both offer you a lifetime warranty and will give you that Straight-through Wide Open Performance with no restrictions. No restrictions equals better flow, and better flow equals more horsepower.

Question: Do you offer a warranty on all your products?

Answer: Yes, we offer a lifetime warranty on all our MagnaFlow Products with the exception of our XL series mufflers/exhaust, catalytic converters and our titanium performance exhaust, which offer a limited warranty.
